Mylan EpiPen Recall Spreads to U.S. | Fortune.com

The company said that some of devices may contain a defective part that prevents the injector from activating in the event of an allergic reaction.

“While the number of reported failures is small, EpiPen products that potentially contain a defective part are being recalled because of the potential for life-threatening risk if a severe allergic reaction goes untreated,” the company said in a statement.
